European natural gas prices are heading for their largest weekly gain in over two years, climbing roughly 20%. A sudden shift in market sentiment is driving the rally, as traders scramble to cover short positions. This buying frenzy coincides with a spell of unusually cold weather across the continent.

The move reflects a classic supply-and-demand squeeze. Europe entered winter with robust storage levels after last year's crisis, but cold snaps are forcing heavier-than-expected withdrawals. This has exposed lingering vulnerabilities in the market, where any hint of tight supply can trigger swift price reactions.

Traders are now watching storage levels and weather forecasts closely. A prolonged cold period could further deplete inventories, while a mild turn might quickly reverse gains. The volatility underscores the delicate balance Europe must maintain to avoid a repeat of last year's energy crisis.
